Anna Paquin and her husband, "True Blood" co-star Stephen Moyer, are expecting their first child together. The couple tied the knot in 2010 and it will be the first child for 29-year-old Paquin and the third for Moyer.

The pair are also an item on "True Blood" where they star as Sookie and Bill. The series returns for its fifth season on June 10 and while speaking with MTV Moyer revealed he would be excited to further develop Bill's relationship with Eric Northman, played by Alexander Skarsgård.

"My missus got to have a go with him last year, so I think it's my turn," Moyer joked. "I know [Alex] is very excited about that."

Skarsgård also noted that he would be thrilled to see where the relationship between the two characters can go:

"That's been fun. Stephen is awesome. I love working with him," Skarsgård said. "It's an interesting dynamic between those two guys, those two characters. I could see that. I don't know. I haven't read — they're breaking season five now, so I don't know what's going to happen, but I'm sure there's going to be some nice Bill and Eric moments."
